Synthesis and Deformable Hierarchical Nanostructure of Intrinsically Stretchable ABA Triblock Copolymer Composed of Poly(3-hexylthiophene) and Polyisobutylene Segments

A novel intrinsically stretchable ABA triblock copolymer can be synthesized where A and B are poly(3-hexylthiophene) (P3HT) and polyisobutylene (PIB) segments, respectively. The deformation of the self-assembled hierarchical nanostructure of the block copolymer thin film was clearly observed by grazing incidence small- and wide-angle X-ray scattering.
